Immune System

The presence of something that shouldn't be there like bad bacteria, viruses and fungi.

Also your immune system does not only become active when under threat much of it patrols your body keeping you healthy specialised T-cells and B-cells enable you to be immune to things that you have encountered before as they become memory cells keeping lookout for whatever triggered them in the first place and to quickly call for reinforcements should you experience it again.

Other cells such as Destroyer cells are your 1st line of defence which find infected cells kill what's inside by destroying that cell unfortunely they destroy many others nearby creating alot of collateral damage for instance when you have a cold and you get a you get a sore throat that is evidence that your destroyer cells have been hard at work.

With an immune response.

When particles of a virus enter our body and are identified by the immune system as foreign "invaders", our bodies use the invaders, which are also called antigens/antibody generators, as a template to create matching antibodies. Antibodies (also called immunoglobulins) are sort of like a lock and key system that, when matched perfectly with the antigens, can "lock" or neutralize the antigens so they can no longer enter or damage our cells. To neutralize each different strain of organism, the antibodies must have the right pattern to match the characteristics of each antigen. A match will allow the antibodies and immune response to make a "lock" to fit those viruses. Our body remembers each new virus pattern that has caused an immune response in the past (either from getting an infection or from vaccinations), so that it can make those matching cells to protect us from that same specific flu strain (or strains that are very similar) in case it ever enters the body again in the future.

Our body has the ability to determine when a virus has invaded and, if it has a match to that strain of virus stored from a prior invasion, the immune response is generated and the immune system quickly makes up a lot of those attack cells (antibodies), that the body made and that worked in the past to destroy/neutralize the invading virus particles. If it is a new invading virus, usually our body can make cells that can match just right in a week to ten days. (It can sometimes do this even more quickly for bacteria and other microbes.)

It is during this time period, when our body is matching and making the attack cells to "kill" the invader, that we feel sick until our body finds the key pattern of cells that will match and lock that specific virus. Our immune system wastes no time in locking up the invading organism, because it knows already what antibodies will work. That is why, once we have had a flu virus like Swine Flu before, we won't get sick from it again. Our body will already know what cells to make and will send them out to destroy the invader even before it can make us feel sick.

B cells (humoral immunity) differentiate into plasma cells which synthesize antibodies.

A phagocyte is a cell that "eats" something, like for example a pathogen/ antigen. Like a pacman kind of cell (sorry for being a child of my generation ;-). Now, being a lymphocyte says nothing more than that the cell is a part of the humoral immune system. And since a B-lymphocyte eats an antigen in its process of immunological defence, it is also a phagocyte. Hence, phagocyte is a classification that decribes the MO of the cell.

There are also other phagocytes like for example macrophages (they eat a lot), monocytes or dendritic cells.

It means your immune system begins to attack your body's own healthy cells and tissues, when it is only supposed to attack viruses and bacteria that might cause you harm. Check out auto immunity

You can apply cold packs to it to try and reduce the swelling. It all depends on what caused the swelling in the first place.

You can also apply smashed potato paste on the location and put a bandage and leave it ovr night. Next day the swelling will reduce.

Endoplasmic Reticulum (ER)

This is a membranous network of tubes and sacs. Smooth ER synthesizes lipids, processes toxins and drugs in the liver cells, and stores and releases calcium ions in muscle cells. Rough ER manufactures membranes, and ribosomes on its surface produce proteins that are secreted, inserted into membranes, or transported in vesicles to other organelles.

No, not even close.

White blood cells are cells that circulate in your blood and lymph.

B-cells are a type of white blood cell that start producing antibodies when they are shown what the antibody is needed for. For example, if your body has a bacterial infection, other cells 'pick up' debris from these bacterial cells, and 'show' these debris pieces to the B-cells. These B-cells then transform into 'plasma cells', which start producing antibodies specific for that particular bacteria.

Antibodies basically 'stick' to any of that same bacteria that they find around your body, acting as a flag, so that your other immune cells can find it and attack it.

Neutrophils is the first phagocytes to migrate into the injured area. Macrophages is the phagocytic offspring of monocytes. The second line of defense is the inflammatory response, mast cells, fluid, and phagocytosis.

they're called phagocytes (literally, phago = eat, cytes = cells)

If your body could not produce antibodies, it would not be able to fight infection. This could cause death in the event that you became sick.

No. Hapten is an antigen whic has low molecular weight and does not trigger immune system.

He noticed, in his village where he was a doctor, that the dairymaids (woman who milk the cow) who had previously had Cowpox didn't get Smallpox. He got inspired by that and thought that they might have become immune to it. He also successfully tested this on a boy.

One day Edward was studying a milk woman who was milking a cow when he noticed she had cow pox that you get from cows. Smallpox was very common in those days so he started to wonder why most milk woman had not caught it yet? So he decided to test it on someone . he found a little boy just 8 and a bit years old and he agreed to help him. He deliberately gave him cow pox and the boy was ill with cow pox but he got better quickly . next he gave him some pus out of a small pox boil to see if he caught it. The boy was fine and Edward had found the cure.

I would like to believe that they can be Cancer and HIV/AIDS, since seeing that the body's immune system would be broken down/damaged and would not be able to defend the body (HIV/AIDS).I am not sure the reason for cancer

If your toe is turning outwards, bunions may be the cause. A bunion is an overgrowth of bone or tissue.

It definitely weakens your immune system! I contracted MRSA 4 years ago (due to surgery) and it took over a year after being off of IV antibiotics to build up my system enough that I would not have to go to the dr everytime I got a cold. I just could not fight anything off! Even now, I have a hard time kicking a minor cold.

B cells release antibodies that attach to foreign invaders and mark them for destruction by phagocytes.

Histamine is the primary effector substance released by the mast cell in response to an allergy. When you have an allergy to something, you exhibit certain common symptoms. Sneezing, itchy and watery eyes, an itchy throat, a runny nose, and itchy rashes are all possible symptoms of an allergy. and the best way to combat these symptoms is to use an antihistamine that, as the name suggests, blocks the amount of histamine that is produced by the body

When the leukocyte count is high, the physician should suspect either an infection or cancer, as these are the two most common reasons for an elevated leukocyte count. Depending upon the rest of the physical examination and the results of the rest of the blood tests, your physician may already know which of the two it is.

Mosquitoes, shopping carts,

antibodies is an virus that can cause to get sick. or it can can cause to get in your body as cells
